I have never heard of these before (heard of GP, just not the model) but as a self confessed Fiat nut, it is something that I will investigate.
Given this is an ETA movement, can anyone shed any light on what movement the Ferrari editions were? If they were in house, and can be picked up for similar money on Chrono24 both circa £2k, then branding aside, the Ferrari models would seem better value and/or the ETA Fiat model over priced. However, because these are given to staff and not sold to the public, means they have had to find their own second hand market value. £1400 sounds like a good price, but then I am bias. Servicing an ETA movement would cost a lot less than an in house GP movement too!
Lets just hope it has better rust proofing than my X19!
